Methods

Cast

Cast<T1, T2>(this, type): T1
Casts this object to the specified type. Throws error on failure.
Type Parameters
- T1
  The target type of the cast.
- T2
  The type of the object to cast.
Parameters
- this: T2
- type: TypeRef<T1>
  The type to cast to.
Returns T1
Inherited from ReplaceValuesBaseTransformation.Cast

Equals

Equals(obj): boolean
Determines whether the specified object is equal to the current object.
Parameters
- obj: any
  The object to compare with the current object.
Returns boolean
true if the specified object is equal to the current object; otherwise, false.

Inherited from ReplaceValuesBaseTransformation.Equals

GetHashCode

GetHashCode(): number
Serves as the default hash function.

Returns number
A hash code for the current object.

Inherited from ReplaceValuesBaseTransformation.GetHashCode

ToString

ToString(): string
Returns a string that represents the current object.

Returns string
A string that represents the current object.

Inherited from ReplaceValuesBaseTransformation.ToString

TryCast

TryCast<T1, T2>(this, type): null | T1
Casts this object to the specified type. Returns null on failure.
Type Parameters
- T1
  The target type of the cast.
- T2
  The type of the object to cast.
Parameters
- this: T2
- type: TypeRef<T1>
  The type to cast to.
Returns null | T1
Inherited from ReplaceValuesBaseTransformation.TryCast

`Static`Equals

Equals(objA, objB): boolean
Determines whether the specified object instances are considered equal.
Parameters
- objA: any
  The first object to compare.
- objB: any
  The second object to compare.
Returns boolean
true if the objects are considered equal; otherwise, false. If both objA and objB are null, the method returns true.

constructor

new ReplaceSpecificValueTransformation(column, originalValue, newValue, rowIdentifyingColumns, rowIdentifyingColumnValues, warnWhenReplacingMultipleValues): ReplaceSpecificValueTransformation
Initializes a new instance of the Spotfire.Dxp.Data.Transformations.ReplaceSpecificValueTransformation class.
Parameters
- column: DataColumnSignature
  The Spotfire.Dxp.Data.DataColumnSignature for the column to be changed.
- originalValue: any
  The value to be replaced in the column.
- newValue: any
  The new value.
- rowIdentifyingColumns: OrExplicit<System.Collections.Generic.IEnumerable<DataColumnSignature>>
  A list of Spotfire.Dxp.Data.DataColumnSignature for columns used to define the rows which contain the values to be replaced.
- rowIdentifyingColumnValues: any[] | OrExplicit<System.Collections.Generic.IEnumerable<any>>
  The values identifying the rows for the row identifying columns.
- warnWhenReplacingMultipleValues: boolean | Boolean
  A value indicating whether a warning should be shown when the transformation replaces more than one value.
