Constructor & Destructor Documentation

◆ DataExtractor()

llvm::DataExtractor::DataExtractor	(	StringRef	Data,
		bool	IsLittleEndian,
		uint8_t	AddressSize
	)

inline

Construct with a buffer that is owned by the caller.

This constructor allows us to use data that is owned by the caller. The data must stay around as long as this object is valid.

Definition at line 51 of file DataExtractor.h.

Member Function Documentation

◆ getAddress()

uint64_t llvm::DataExtractor::getAddress ( uint32_t * offset_ptr ) const

inline

Extract an pointer from *offset_ptr.

Extract a single pointer from the data and update the offset pointed to by offset_ptr. The size of the extracted pointer is getAddressSize(), so the address size has to be set correctly prior to extracting any pointer values.

Parameters

[in,out] offset_ptr A pointer to an offset within the data that will be advanced by the appropriate number of bytes if the value is extracted correctly. If the offset is out of bounds or there are not enough bytes to extract this value, the offset will be left unmodified.

Returns: The extracted pointer value as a 64 integer.

◆ getAddressSize()

uint8_t llvm::DataExtractor::getAddressSize ( ) const

inline

Get the address size for this extractor.

◆ getCStr()

const char * DataExtractor::getCStr ( uint32_t * offset_ptr ) const

Extract a C string from *offset_ptr.

Returns a pointer to a C String from the data at the offset pointed to by offset_ptr. A variable length NULL terminated C string will be extracted and the offset_ptr will be updated with the offset of the byte that follows the NULL terminator byte.

Parameters

[in,out] offset_ptr A pointer to an offset within the data that will be advanced by the appropriate number of bytes if the value is extracted correctly. If the offset is out of bounds or there are not enough bytes to extract this value, the offset will be left unmodified.

Returns: A pointer to the C string value in the data. If the offset pointed to by offset_ptr is out of bounds, or if the offset plus the length of the C string is out of bounds, NULL will be returned.

◆ getCStrRef()

StringRef DataExtractor::getCStrRef ( uint32_t * OffsetPtr ) const

Extract a C string from *OffsetPtr.

Returns a StringRef for the C String from the data at the offset pointed to by OffsetPtr. A variable length NULL terminated C string will be extracted and the OffsetPtr will be updated with the offset of the byte that follows the NULL terminator byte.

Parameters

[in,out] OffsetPtr A pointer to an offset within the data that will be advanced by the appropriate number of bytes if the value is extracted correctly. If the offset is out of bounds or there are not enough bytes to extract this value, the offset will be left unmodified.

Returns: A StringRef for the C string value in the data. If the offset pointed to by OffsetPtr is out of bounds, or if the offset plus the length of the C string is out of bounds, a default-initialized StringRef will be returned.

int64_t DataExtractor::getSigned	(	uint32_t *	offset_ptr,
		uint32_t	size
	)		const

Extract an signed integer of size byte_size from *offset_ptr.

Extract a single signed integer value (sign extending if required) and update the offset pointed to by offset_ptr. The size of the extracted integer is specified by the byte_size argument. byte_size should have a value greater than or equal to one and less than or equal to eight since the return value is 64 bits wide. Any byte_size values less than 1 or greater than 8 will result in nothing being extracted, and zero being returned.

Parameters

[in,out]	offset_ptr	A pointer to an offset within the data that will be advanced by the appropriate number of bytes if the value is extracted correctly. If the offset is out of bounds or there are not enough bytes to extract this value, the offset will be left unmodified.
[in]	size	The size in bytes of the integer to extract.

Returns: The sign extended signed integer value that was extracted, or zero on failure.
