Kitto.RB.ppStorePipe

TppKStorePipeline class

ReportBuilder data pipeline that feeds a KittoX in-memory store (TKStore) to a ppReport. Adapts TKRecord/TKField to the ppReport pipeline contract, so reports can be run directly against Kitto stores without a dataset.

constructor CreatePipeline(aOwner: TComponent;

Creates the pipeline bound to the given store and (optional) single record, with the specified ppReport pipeline name.

procedure FreeBookmark(aBookmark: NativeInt);

Releases a bookmark previously obtained via GetBookmark.

function GetBookmark: NativeInt;

Returns a bookmark for the current record position.

function GetDataSetName: String;

Returns the pipeline's data set name.

function GetFieldIsCalculated(aFieldName: String): Boolean;

Returns True if the named field is a calculated field.

function GetFieldNames(aFieldNameList: TStrings): Boolean;

Fills the list with the names of the store's fields.

function GetFieldAsDouble(aFieldName: String): Double;

Returns the named field of the current record as a Double.

function GetFieldAsGuid(aFieldName: String): TGUID;

Returns the named field of the current record as a TGUID.

procedure GetFieldAsStream(aFieldName: String;

Writes the named field of the current record into the given stream.

function GetFieldAsPicture(aFieldName: String): TPicture;

Returns the named field of the current record as a TPicture.

function GetFieldAsString(aFieldName: String): String;

Returns the named field of the current record as a string.

function GetFieldDataType(aFieldName: String): TppDataType;

Returns the ppReport data type of the named field.

function GetFieldIsNull(aFieldName: String): Boolean;

Returns True if the named field of the current record is null.

function GetFieldValue(aFieldName: string): Variant;

Returns the named field of the current record as a Variant.

procedure GotoBookmark(aBookmark: NativeInt);

Moves the current record position to the given bookmark.

TraTppKStorePipelineRTTI class

ppReport RTTI helper that exposes TppKStorePipeline properties to the ReportBuilder RAP scripting engine at design/run time.

class function GetPropRec(aClass: TClass;

Returns the RAP property descriptor for the named property.

class function GetPropValue(aObject: TObject;

Reads the named property value from the object for the RAP engine.

class function RefClass: TClass;

Returns the class (TppKStorePipeline) this RTTI helper describes.

class function SetPropValue(aObject: TObject;

Writes the named property value on the object from the RAP engine.

Routines

function ppConvertFieldType(aFieldType: TEFDataType): TppDataType;

Maps an EF data type to the corresponding ppReport field data type.
