Fields

Predicates

toString

Gets a textual representation of this control flow node.

Inherited predicates

dominatesNode

Holds if this node dominates dominee in the control-flow graph.

from Node
getAPredecessor

Gets a node that directly precedes this one in the control-flow graph.

from Node
getASuccessor

Gets a node that directly follows this one in the control-flow graph.

from Node
getBasicBlock

Gets the basic block to which this node belongs.

from Node
getBoolValue

Gets the Boolean value of the result of this instruction, if it can be determined.

from Instruction
getExactValue

from Instruction
getIntValue

Gets the int value of the result of this instruction, if it can be determined.

from Instruction
getNumericValue

Gets either getFloatValue or getIntValue

from Instruction
getResultType

Gets the type of the result of this instruction, if any.

from Instruction

from Node
isJoin

Holds if this is a node with more than one predecessor.

from Node
isPlatformIndependentConstant

Holds if the result of this instruction is known at compile time, and is guaranteed not to depend on the platform where it is evaluated.

from Instruction
reads

from Instruction
readsElement

Holds if this instruction reads the value of element index on the value of base.

from Instruction
readsField

Holds if this instruction reads the value of field f on the value of base.

from Instruction
readsMethod
