Synopsis

Description
The Apache Traffic Server API provides large number of types. Many of them are specific to a particular API function or function group, but others are used more widely. Those are described on this page.
-
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
An opaque type that represents a Traffic Server continuation.
-
type TSEventFunc
-
type TSFile
-
type TSHostLookupResult
A type representing the result of a call to
TSHostLookup()
. Use withTSHostLookupResultAddrGet()
.
-
type TSHRTime
“High Resolution Time”
A 64 bit time value, measured in nanoseconds.
-
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()
andTSIOBufferWaterMarkSet()
functions for further detail.
-
TSConnectType connect_type
-
type TSConnectType
Enumeration that specifies the type of data within a
TSHttpConnectOptions
structure.
-
type TSHttpParser
-
type TSHttpTxn
An opaque type that represents a Traffic Server HTTP transaction.
-
type TSIOBuffer
-
type TSIOBufferBlock
-
type TSIOBufferReader
-
type TSIOBufferSizeIndex
-
type TSIOBufferWaterMark
An enumeration that contains valid watermark values, currently only defaults.
-
type TSLifecycleHookID
An enumeration that identifies a life cycle hook.
-
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
The type used internally for a floating point value. This corresponds to the value
TS_RECORDDATATYPE_FLOAT
forTSRecordDataType
.
-
type TSMgmtInt
The type used internally for an integer. This corresponds to the value
TS_RECORDDATATYPE_INT
forTSRecordDataType
.
-
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 thatTSMBuffer
instance. It identifies a specific object in theTSMBuffer
. This indirection is needed so that theTSMBuffer
can reallocate space as needed. Therefore a raw address obtained from aTSMLoc
should be considered volatile that may become invalid across any API call.
-
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.
-
unsigned long size
-
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 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 callingTSHttpTxnClientReqGet()
.
-
int redirect
Flag for using the remapped URL as an explicit redirection. This can be set by the remap plugin.
-
TSMBuffer requestBufp
-
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.
-
const char *cert_name;
-
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 aTSThread
and can be passed as an argument to any parameter of typeTSThread
.
-
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.
-
enumerator TS_UUID_V4
-
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.
-
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.
-
short int ink_major
-
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 thatTSHttpPriority
is at least as large asTSHttp2Priority
. As other structures are added that are represented byTSHttpPriority
add more static_asserts to verify thatTSHttpPriority
is as large as it needs to be.
-
uint8_t priority_type
