Detailed Description

Subtable, pattern, and context information applied across a with block.

The header of a with block is applied to all constructors in the block. It attaches each constructor to a specific subtable. A pattern expression and/or a a series of context changes is attached to each constructor as well.

collectAndPrependContext()

vector< ContextChange * > * ghidra::WithBlock::collectAndPrependContext ( const list< WithBlock > &  stack, vector< ContextChange *> *  contvec  )

static

Build a complete array of context changes from any surrounding with blocks.

Given a list of ContextChanges parsed locally from a Constructor and the stack of surrounding with blocks, make a new list of ContextChanges, prepending everything from the stack to the local vector. Return the new list and delete the old.

Parameters

stack	is the current with block stack
contvec	is the local list of ContextChanges (or null)

Returns

the new list of ContextChanges

collectAndPrependPattern()

PatternEquation * ghidra::WithBlock::collectAndPrependPattern ( const list< WithBlock > &  stack, PatternEquation *  pateq  )

static

Build a complete pattern equation from any surrounding with blocks.

Given the pattern equation parsed locally from a Constructor and the stack of surrounding with blocks, create the final pattern equation for the Constructor. Each with block pattern is preprended to the local pattern.

Parameters

stack	is the stack of with blocks currently active at the Constructor
pateq	is the pattern equation parsed from the local Constructor statement

Returns

the final pattern equation

getCurrentSubtable()

SubtableSymbol * ghidra::WithBlock::getCurrentSubtable ( const list< WithBlock > &  stack )

static

Get the active subtable from the stack of currently active with blocks.

Find the subtable associated with the innermost with block and return it.

Parameters

stack

is the stack of currently active with blocks

Returns

the innermost subtable (or null)

set()

void ghidra::WithBlock::set	(	SubtableSymbol *	s,
		PatternEquation *	pq,
		vector< ContextChange *> *	cvec
	)

Set components of the header.

Establish each component of the with block header

Parameters

s	is the subtable (or null)
pq	is the pattern to prepend (or null)
cvec	is the set of context changes (or null)
