MathBOp

public MathBOp(IValueExpression<? extends IV> left,
       IValueExpression<? extends IV> right,
       MathBOp.MathOp op,
       GlobalAnnotations globals)

Parameters:

left - The left operand.

right - The right operand.

op - The annotation specifying the operation to be performed on those operands.

MathBOp

public MathBOp(BOp[] args,
       Map<String,Object> anns)

Required shallow copy constructor.

Parameters:

args - The operands.

op - The operation.

MathBOp

Constructor required for com.bigdata.bop.BOpUtility#deepCopy(FilterNode).

Parameters:

op -

Method Detail

get

public final IV get(IBindingSet bs)

Description copied from interface: IValueExpression

Return the as bound value of the variable, constant, or expression. The as bound value of an IConstant is the contant's value. The as bound value of an IVariable is the bound value in the given IBindingSet -or- null if the variable is not bound in the IBindingSet.

Specified by:

get in interface IValueExpression

Parameters:

bs - The binding set.

Returns:

The as bound value of the constant, variable, or expression.

left

public IValueExpression<? extends IV> left()

right

public IValueExpression<? extends IV> right()

op

public MathBOp.MathOp op()

vf

public BigdataValueFactory vf()

toString

public String toString()

Description copied from class: CoreBaseBOp

Return a non-recursive representation of the arguments and annotations for this BOp.

Specified by:

toString in interface BOp

Overrides:

toString in class CoreBaseBOp

equals

public final boolean equals(MathBOp m)

equals

public final boolean equals(IVValueExpression o)

hashCode

public int hashCode()

Description copied from class: CoreBaseBOp

The hash code is based on the hash of the operands (cached).

Overrides:

hashCode in class CoreBaseBOp

getRequirement

public INeedsMaterialization.Requirement getRequirement()

The MathBOp can work on inline numerics. It is only when the operands evaluate to non-inline numerics that this bop needs materialization.

Specified by:

getRequirement in interface INeedsMaterialization
