Detailed Description

Helper class for resolving cross-references while deserializing BlockGraph objects.

FlowBlock objects are serialized with their associated index value and edges are serialized with the indices of the FlowBlock end-points. During deserialization, this class maintains a list of FlowBlock objects sorted by index and then looks up the FlowBlock matching a given index as edges specify them.

createBlock()

FlowBlock * ghidra::BlockMap::createBlock

(

const string &

name

)

Create a FlowBlock of the named type.

Given the name of a block (deserialized from a <bhead> tag), build the corresponding type of block.

Parameters

name	is the name of the block type

Returns

a new instance of the named FlowBlock type

findBlock()

FlowBlock * ghidra::BlockMap::findBlock ( const vector< FlowBlock * > &  list, int4  ind  )

staticprivate

Locate a FlowBlock with a given index.

Given a list of FlowBlock objects sorted by index, use binary search to find the FlowBlock with matching index

Parameters

list	is the sorted list of FlowBlock objects
ind	is the FlowBlock index to match

Returns

the matching FlowBlock or NULL
