All Implemented Interfaces:
Cloneable
public class MathTask extends org.apache.tools.ant.Task
Provides basic math functions. Simple calculations can be done via attributes only, more complex formulas can be set up via nested Ops.

    • setResult

      public void setResult(String name)
      Sets the name of the property to store the result in. This is stored in a user property, so is reusable.
      Parameters:
      name - the name of a property to set for a result.

    • setDatatype

      public void setDatatype(String type)
      Sets the datatype of this calculation. Allowed values are "int", "long", "float", or "double". Optional, if used, will be applied to all numbers in this math operation.

    • setOperand1

      public void setOperand1(String op) throws org.apache.tools.ant.BuildException
      Set an operand as an attribute. This is for convenience, if used, it overrides any nested Ops. Must parse to a number.
      Throws:
      org.apache.tools.ant.BuildException

    • setOperand2

      public void setOperand2(String op) throws org.apache.tools.ant.BuildException
      Set an operand as an attribute. This is for convenience, if used, it overrides any nested Ops. Must parse to a number.
      Throws:
      org.apache.tools.ant.BuildException

    • setOperation

      public void setOperation(String op)
      Set an operation as an attribute. This is for convenience, if used, it overrides any nested Ops.
      Parameters:
      op - any operation allowed by Op.

    • addConfiguredOp

      public void addConfiguredOp(Op op)
      Add a nested operation. Only one operation is allowed at a time.
      Parameters:
      op - the operation to add.

    • setStrict

      public void setStrict(boolean b)
      Use the StrictMath library.

    • execute

      public void execute()
      Overrides:
      execute in class org.apache.tools.ant.Task
