Flush buffered input and/or output, with signal propagation.
hardFlush | is used to indicate whether all data should be flushed |
propagation | the number of attached transformations the Flush() signal should be passed |
blocking | specifies whether the object should block when processing input |
propagation count includes this object. Setting propagation to 1
means this object only. Setting propagation to -1
means unlimited propagation.
Implements CustomFlushPropagation< Filter >.

virtual |
Initialize or reinitialize this object, without signal propagation.
parameters | a set of NameValuePairs to initialize this object |
NotImplemented |
IsolatedInitialize() is used to initialize or reinitialize an object using a variable number of arbitrarily typed arguments. The function avoids the need for multiple constructors providing all possible combintations of configurable parameters.
IsolatedInitialize() does not call Initialize() on attached transformations. If initialization should be propagated, then use the Initialize() function.
If a derived class does not override IsolatedInitialize(), then the base class throws NotImplemented.
Reimplemented from BufferedTransformation.
Definition at line 318 of file ida.cpp.
|
virtual |
Input multiple bytes for processing.
inString | the byte buffer to process |
length | the size of the string, in bytes |
messageEnd | means how many filters to signal MessageEnd() to, including this one |
blocking | specifies whether the object should block when processing input |
Derived classes must implement Put2().
