All Implemented Interfaces:

JsonTableColumn

public record JsonTableQueryColumn(int outputIndex, ResolvedFunction function, IrJsonPath path, long wrapperBehavior, long emptyBehavior, long errorBehavior)
extends Record
implements JsonTableColumn

This representation does not contain all properties of the column as specified in json_table invocation. Certain properties are handled by the output function which is applied later. These are: output format and quotes behavior.

Constructor Details

JsonTableQueryColumn

public JsonTableQueryColumn(int outputIndex,
 ResolvedFunction function,
 IrJsonPath path,
 long wrapperBehavior,
 long emptyBehavior,
 long errorBehavior)

Creates an instance of a JsonTableQueryColumn record class.

Parameters:

outputIndex - the value for the outputIndex record component

function - the value for the function record component

path - the value for the path record component

wrapperBehavior - the value for the wrapperBehavior record component

emptyBehavior - the value for the emptyBehavior record component

errorBehavior - the value for the errorBehavior record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

outputIndex

public int outputIndex()

Returns the value of the outputIndex record component.

Returns:

the value of the outputIndex record component

function

public ResolvedFunction function()

Returns the value of the function record component.

Returns:

the value of the function record component

path

public IrJsonPath path()

Returns the value of the path record component.

Returns:

the value of the path record component

wrapperBehavior

public long wrapperBehavior()

Returns the value of the wrapperBehavior record component.

Returns:

the value of the wrapperBehavior record component

emptyBehavior

public long emptyBehavior()

Returns the value of the emptyBehavior record component.

Returns:

the value of the emptyBehavior record component

errorBehavior

public long errorBehavior()

Returns the value of the errorBehavior record component.

Returns:

the value of the errorBehavior record component
