Detailed Description
Data defining a specific memory location.
Within the decompiler's model of a processor, any register, memory location, or other variable can always be represented as an address space, an offset within the space, and the size of the sequence of bytes. This is more commonly referred to as a Varnode, but this is a bare-bones container for the data that doesn't have the cached attributes and the dataflow links of the Varnode within its syntax tree.
Member Function Documentation
◆ contains()
| bool VarnodeData::contains | ( | const VarnodeData & | op2 | ) | const |
Does this container another given VarnodeData.
Return true, if this, as an address range, contains the other address range
- Parameters
-
op2 is the other VarnodeData to test for containment
- Returns
- true if this contains the other
◆ getAddr()
|
inline |
Get the location of the varnode as an address.
This is a convenience function to construct a full Address from the VarnodeData's address space and offset
- Returns
- the address of the varnode
◆ operator!=()
|
inline |
Compare for inequality.
Compare VarnodeData for inequality. If either the space, offset, or size is not equal, return true.
- Parameters
-
op2 is the object being compared to
- Returns
- true if this is not equal to op2
◆ operator<()
|
inline |
An ordering for VarnodeData.
VarnodeData can be sorted in terms of the space its in (the space's index), the offset within the space, and finally by the size.
- Parameters
-
op2 is the object being compared to
- Returns
- true if this is less than op2
◆ operator==()
|
inline |
Compare for equality.
Compare VarnodeData for equality. The space, offset, and size must all be exactly equal
- Parameters
-
op2 is the object being compared to
- Returns
- true if this is equal to op2
◆ restoreXml()
| void VarnodeData::restoreXml | ( | const Element * | el, |
| const AddrSpaceManager * | manage | ||
| ) |
Recover this object from an XML tag.
Build this VarnodeData from an <addr> tag
- Parameters
-
el is the parsed tag manage is the address space manager
