Detailed Description

A common base class for data-type filters that tests for a size range.

Any filter that inherits from this, can use ATTRIB_MINSIZE and ATTRIB_MAXSIZE to place bounds on the possible sizes of data-types. The bounds are enforced by calling filterOnSize() within the inheriting classes filter() method.

Member Function Documentation

clone()

virtual DatatypeFilter * ghidra::SizeRestrictedFilter::clone ( void  ) const

inlinevirtual

Make a copy of this filter.

Returns

the newly allocated copy

Implements ghidra::DatatypeFilter.

Reimplemented in ghidra::MetaTypeFilter, and ghidra::HomogeneousAggregate.

References maxSize, minSize, and SizeRestrictedFilter().

decode()

void ghidra::SizeRestrictedFilter::decode ( Decoder &  decoder )

virtual

Configure details of the data-type class being filtered from the given stream.

Parameters

decoder

is the given stream decoder

Implements ghidra::DatatypeFilter.

References ghidra::Decoder::getNextAttributeId(), maxSize, minSize, and ghidra::Decoder::readUnsignedInteger().

filter()

virtual bool ghidra::SizeRestrictedFilter::filter ( Datatype *  dt ) const

inlinevirtual

Test whether the given data-type belongs to this filter's data-type class.

Parameters

dt	is the given data-type to test

Returns

true if the data-type is in the class, false otherwise

Implements ghidra::DatatypeFilter.

Reimplemented in ghidra::MetaTypeFilter, and ghidra::HomogeneousAggregate.

References filterOnSize().

filterOnSize()

bool ghidra::SizeRestrictedFilter::filterOnSize

(

Datatype *

dt

)

const

Enforce any size bounds on a given data-type.

If maxSize is not zero, the data-type is checked to see if its size in bytes falls between minSize and maxSize inclusive.

Parameters

dt	is the data-type to test

Returns

true if the data-type meets the size restrictions
