Class ScriptChunk

  • public class ScriptChunk
extends java.lang.Object
    A script element that is either a data push (signature, pubkey, etc) or a non-push (logic, numeric, etc) operation.

    • Field Summary

      Fields 
      Modifier and Type Field Description
      byte[] data
      For push operations, this is the vector to be pushed on the stack.
      int opcode
      Operation to be executed.

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      int decodeOpN()
      If this chunk is an OP_N opcode returns the equivalent integer value.
      boolean equals​(java.lang.Object o)  
      boolean equalsOpCode​(int opcode)  
      int hashCode()  
      boolean isOpCode()
      If this chunk is a single byte of non-pushdata content (could be OP_RESERVED or some invalid Opcode)
      boolean isPushData()
      Returns true if this chunk is pushdata content, including the single-byte pushdatas.
      boolean isShortestPossiblePushData()
      Called on a pushdata chunk, returns true if it uses the smallest possible way (according to BIP62) to push the data.
      int size()  
      byte[] toByteArray()

    • Field Detail

      • opcode

        public final int opcode
        Operation to be executed. Opcodes are defined in ScriptOpCodes.

      • data

        @Nullable
public final byte[] data
        For push operations, this is the vector to be pushed on the stack. For ScriptOpCodes.OP_0, the vector is empty. Null for non-push operations.
