evaluate

public java.lang.Long evaluate(Input<java.lang.Integer>... args)

Description copied from class: Scalar

Evaluate the function using the provided arguments

Specified by:

evaluate in class Scalar<java.lang.Long,java.lang.Integer>

info

public FunctionInfo info()

Description copied from interface: FunctionImplementation

Provides meta information about this function implementation.

Specified by:

info in interface FunctionImplementation

normalizeSymbol

public Symbol normalizeSymbol(Function function,
                              TransactionContext transactionContext)

Description copied from interface: FunctionImplementation

Normalize a symbol into a simplified form. This may return the symbol as is if it cannot be normalized.

Specified by:

normalizeSymbol in interface FunctionImplementation

Overrides:

normalizeSymbol in class Scalar<java.lang.Long,java.lang.Integer>

transactionContext - context which is shared across normalizeSymbol calls during a statement-lifecycle. This will only be present if normalizeSymbol is called on the handler node. normalizeSymbol calls during execution won't receive a StmtCtx

beforeArgs

public java.lang.String beforeArgs(Function function)

Description copied from interface: FunctionFormatSpec

stuff that comes before arguments are formatted

Specified by:

beforeArgs in interface FunctionFormatSpec

afterArgs

public java.lang.String afterArgs(Function function)

Description copied from interface: FunctionFormatSpec

stuff that comes after arguments are formatted

Specified by:

afterArgs in interface FunctionFormatSpec

formatArgs

public boolean formatArgs(Function function)

Description copied from interface: FunctionFormatSpec

whether or not to formatSymbol the arguments

Specified by:

formatArgs in interface FunctionFormatSpec
