JitOperation

public final class JitOperation extends AstExpression

A libcudf JIT operation.

Expressions containing a JIT operation must be compiled with AstExpression.compileJit(). Operator arity, error policy, and target-scale constraints are validated when the expression is compiled.

Constructor Summary

JitOperation(JitOperator op, AstExpression... inputs)	Construct an operation that propagates evaluation errors.
JitOperation(JitOperator op, JitErrorPolicy errorPolicy, AstExpression... inputs)	Construct an operation with an explicit error policy.
JitOperation(JitOperator op, int targetScale, AstExpression... inputs)	Construct a target-scale operation that propagates evaluation errors.

Constructors

public JitOperation(JitOperator op, AstExpression... inputs)

Construct an operation that propagates evaluation errors.

Parameters:

• op – operator to apply

• inputs – operator inputs

Throws:

NullPointerException – if op, inputs, or an input is null

public JitOperation(

JitOperator op,

JitErrorPolicy errorPolicy,

AstExpression... inputs

)

Construct an operation with an explicit error policy.

Parameters:

• op – operator to apply

• errorPolicy – error handling policy

• inputs – operator inputs

Throws:

NullPointerException – if any argument or input is null

public JitOperation(

JitOperator op,

int targetScale,

AstExpression... inputs

)

Construct a target-scale operation that propagates evaluation errors.

The target scale is valid only for JitOperator.RESCALE.

Parameters:

• op – operator to apply

• targetScale – target fixed-point scale

• inputs – operator inputs

Throws:

NullPointerException – if op, inputs, or an input is null
