Detailed Description

An op that displays as an internal string.

The user op takes no input parameters. In the decompiler output, it displays as a quoted string. The string is associated with the address assigned to the user op and is pulled from StringManager as internal.

Member Function Documentation

decode()

virtual void ghidra::InternalStringOp::decode ( Decoder &  decoder )

inlinevirtual

Restore the detailed description from a stream element.

The details of how a user defined operation behaves are parsed from the element.

Parameters

decoder

is the stream decoder

Implements ghidra::UserPcodeOp.

getOutputLocal()

Datatype * ghidra::InternalStringOp::getOutputLocal ( const PcodeOp *  op ) const

virtual

Return the output data-type of the user-op if specified.

Parameters

op	is the instantiation of the user-op

Returns

the data-type or null to indicate the data-type is unspecified

Reimplemented from ghidra::UserPcodeOp.
