public int consumeStack(ConstantPool cpg)

Overrides org.aspectj.apache.bcel.generic.InvokeInstruction.consumeStack.

Doc from org.aspectj.apache.bcel.generic.InvokeInstruction.consumeStack.

Also works for instructions whose stack effect depends on the constant pool entry they reference.

Returns:int

Number of words consumed from stack by this instruction

public void dump(DataOutputStream out) throws IOException

Overrides org.aspectj.apache.bcel.generic.InstructionCP.dump.

Dump instruction as byte code to stream out.

Parameters
out:DataOutputStream

Output stream

equalsback to summary
public boolean equals(Object other)

Overrides org.aspectj.apache.bcel.generic.InstructionCP.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

getCountback to summary
public int getCount()

The count argument according to the Java Language Specification, Second Edition.

hashCodeback to summary
public int hashCode()

Overrides org.aspectj.apache.bcel.generic.InstructionCP.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object.

toStringback to summary
public String toString(ConstantPool cp)

Overrides org.aspectj.apache.bcel.generic.InvokeInstruction.toString.

Returns:String

mnemonic for instruction with symbolic references resolved
