Method Details

getNumberOfUses

public int getNumberOfUses()

Overrides:

getNumberOfUses in class SSAInstruction

getUse

public int getUse(int j)

Overrides:

getUse in class SSAInstruction

Returns:

value number representing the jth use in this instruction. -1 means TOP (i.e., the value doesn't matter)

getArrayRef

public int getArrayRef()

Return the value number of the array reference.

getIndex

public int getIndex()

Return the value number of the index of the array reference.

getElementType

public TypeReference getElementType()

typeIsPrimitive

public boolean typeIsPrimitive()

Returns:

true iff this represents an array access of a primitive type element

isPEI

public boolean isPEI()

Overrides:

isPEI in class SSAInstruction

Returns:

true iff this instruction may throw an exception.

isFallThrough

public boolean isFallThrough()

Specified by:

isFallThrough in class SSAInstruction

Returns:

true iff this instruction may fall through to the next
