TSAPI 型

概要

#include <ts/ts.h>
#include <ts/remap.h>

解説

Apache Traffic Server API は多数の型を提供します。それらの多くは特定の API 関数や関数グループに固有のものですが、それ以外はより広範囲で使用されます。それらはこのページで解説されます。

type ink_hrtime

type INK_MD5

Buffer type sufficient to contain an MD5 hash value.

class RecRawStatBlock

A data block intended to contain Traffic Server statistics.

type TSAction

type TSCacheKey

type TSConfig

type TSCont

Traffic Server の継続を表現する不明瞭な型。

type TSEventFunc

type TSFile

type TSHostLookupResult

A type representing the result of a call to TSHostLookup(). Use with TSHostLookupResultAddrGet().

type TSHRTime

"高精度の時間"

ナノ秒で計られた 64 ビットの時間値。

type TSHttpConnectOptions

A type that encapsulates options passed into the TSHttpConnectPlugin() function.

TSConnectType connect_type

The type of data represented in the struct.

sockaddr const *addr

Network address of the target of the connection.

const char *tag

Tag that is passed through to the HTTP state machine.

int64_t id

Numeric identifier passed through to the HTTP state machine.

TSIOBufferSizeIndex buffer_index

A numeric buffer size index used to derive actual sizes used when constructing IOBuffers; see TSIOBufferSizeIndex.

TSIOBufferWaterMark buffer_water_mark

A numeric value specifying the minimum number of bytes that must be written to an IOBuffer before any continuation is called back to read from the buffer. See the TSIOBufferWaterMarkGet() and TSIOBufferWaterMarkSet() functions for further detail.

type TSConnectType

Enumeration that specifies the type of data within a TSHttpConnectOptions structure.

type TSHttpParser

type TSHttpSsn

Traffic Server session を表現する不明瞭な型。

type TSHttpTxn

Traffic Server HTTP transaction を表現する不明瞭な型。

type TSIOBuffer

type TSIOBufferBlock

type TSIOBufferReader

type TSIOBufferSizeIndex

type TSIOBufferWaterMark

An enumeration that contains valid watermark values, currently only defaults.

type TSMBuffer

Internally, data for a transaction is stored in one or more header heaps. These are storage local to the transaction, and generally each HTTP header is stored in a separate one. This type is a handle to a header heap, and is provided or required by functions that locate HTTP header related data.

type TSMgmtCounter

type TSMgmtFloat

内部で浮動小数点の値として使われる型。これは TSRecordDataType の TS_RECORDDATATYPE_FLOAT に相当します。

type TSMgmtInt

内部で整数として使われる型。これは TSRecordDataType の TS_RECORDDATATYPE_INT に相当します。

type TSMgmtString

type TSMimeParser

type TSMLoc

This is a memory location relative to a header heap represented by a TSMBuffer and must always be used in conjunction with that TSMBuffer instance. It identifies a specific object in the TSMBuffer. This indirection is needed so that the TSMBuffer can reallocate space as needed. Therefore a raw address obtained from a TSMLoc should be considered volatile that may become invalid across any API call.

TSMLoc TS_NULL_MLOC

A predefined null valued TSMLoc used to indicate the absence of an TSMLoc.

type TSMutex

type TSPluginRegistrationInfo

The following struct is used by TSPluginRegister().

It stores registration information about the plugin.

type TSRemapInterface

Data passed to a remap plugin via TSRemapInit().

unsigned long size

The size of the structure in bytes, including this member.

unsigned long tsremap_version

The API version of the C API. The lower 16 bits are the minor version, and the upper bits the major version.

TSRemapPluginInfo plugin_info

An opaque object, which holds various details about the currently loaded and running plugin. You can't access the details directly, but rather must call an access function such as TSRemapDLHandleGet().

type TSRemapPluginInfo

Opaque data passed to a remap plugin via TSRemapInit() in the plugin_info member above.

type TSRemapRequestInfo

Data passed to a remap plugin during the invocation of a remap rule.

TSMBuffer requestBufp

The client request. All of the other TSMLoc values use this as the base buffer.

TSMLoc requestHdrp

The client request.

TSMLoc mapFromUrl

The match URL in the remap rule.

TSMLoc mapToUrl

The target URL in the remap rule.

TSMLoc requestUrl

The current request URL. The remap rule and plugins listed earlier in the remap rule can modify this from the client request URL. Remap plugins are expected to modify this value to perform the remapping of the request. Note this is the same TSMLoc as would be obtained by calling TSHttpTxnClientReqGet().

int redirect

Flag for using the remapped URL as an explicit redirection. This can be set by the remap plugin.

type TSSecretID

Contains the data for a TLS certificate and key.

const char *cert_name

The TLS certificate name.

size_t cert_name_len

The length of the TLS certificate name.

const char *key_name

The name of the TLS key.

size_t key_name_len

The length of the name of the TLS key.

type TSSslX509

This type represents the X509 object created from an SSL certificate.

type TSTextLogObject

This type represents a custom log file that you create with TSTextLogObjectCreate().

Your plugin writes entries into this log file using TSTextLogObjectWrite().

type TSThread

This represents an internal Traffic Server thread, created by the Traffic Server core. It is an opaque type which can be used only to check for equality / inequality, and passed to API functions. An instance that refers to the current thread can be obtained with TSThreadSelf().

type TSEventThread

This type represents an event thread. It is an opaque which is used to specify a particular event processing thread in Traffic Server. If plugin code is executing in an event thread (which will be true if called from a hook or a scheduled event) then the current event thread can be obtained via TSEventThreadSelf().

A TSEventThread is also a TSThread and can be passed as an argument to any parameter of type TSThread.

type TSThreadFunc

type TSUserArgType

An enum for the supported types of user arguments.

enum TSUuidVersion

A version value for at TSUuid.

enumerator TS_UUID_V4

A version 4 UUID. Currently only this value is used.

size_t TS_UUID_STRING_LEN

Length of a UUID string.

type TSVConn

A virtual connection. This is the basic mechanism for abstracting I/O operations in Traffic Server.

type TSNetVConnection

A subtype of TSVConn that provides additional IP network information and operations.

type TSVIO

type ModuleVersion

A module version.

template<typename T>
class DLL

An anchor for a double linked intrusive list of instance of T.

template<typename T>
class Queue

type TSAcceptor

template<typename T>
class LINK

class VersionNumber

A two part version number, defined in include/tscore/I_Version.h.

short int ink_major

Major version number.

short int ink_minor

Minor version number.

type TSFetchUrlParams_t

type TSFetchSM

type TSFetchEvent

type TSHttpPriority

The abstract type of the various HTTP priority implementations.

uint8_t priority_type

The reference to the concrete HTTP priority implementation. This will be a value from TSHttpPriorityType

uint8_t data[7]

The space allocated for the concrete priority implementation.

Note that this has to take padding into account. There is a static_assert in InkAPI.cc to verify that TSHttpPriority is at least as large as TSHttp2Priority. As other structures are added that are represented by TSHttpPriority add more static_asserts to verify that TSHttpPriority is as large as it needs to be.

type TSHttp2Priority

A structure for HTTP/2 priority. For an explanation of these terms with respect to HTTP/2, see RFC 7540, section 5.3.

uint8_t priority_type

HTTP_PROTOCOL_TYPE_HTTP_2

uint8_t weight

int32_t stream_dependency

The stream dependency. Per spec, see RFC 7540 section 6.2, this is 31 bits. We use a signed 32 bit structure to store either a valid dependency or -1 if the stream has no dependency.
