Table

A table is a data structure that allows editing of a look up table with a TableEditor. It uses a list of graph points to create a path which is rendered to a float array of the desired size.

Public types

enum DataType

Name	Description
Midi	in this mode, the table contains 128 elements and can be used for everything midi-related.
SampleLookupTable	in this mode, the table contains 2048 elements and can be used for holding everything sample-related (waveforms, envelopes, etc.)

Class methods

Table

Table()

Creates a new table of the specified type.

getTableSize

int getTableSize() const =0

Overwrite this and return the table size.

setGraphPoints

void setGraphPoints(const Array< GraphPoint > &newGraphPoints, int numPoints)

Sets the GraphPoints. If you need to refresh the internal table, you also have to call fillLookUpTable() .

exportData

String exportData() const

Exports the data as base64 encoded String. This is not a ValueTree (so RestorableObject is no base class from Table), because it needs to be embedded in an XML attribute
restoreData()

restoreData

void restoreData(const String &savedString)

Restores the data from a base64 encoded String.
exportData()

getNumGraphPoints

int getNumGraphPoints() const

Returns the number of graph points

getGraphPoint

GraphPoint getGraphPoint(int pointIndex) const

Get a copy of the graph point at pointIndex.

createPath

void createPath(Path &normalizedPath) const

This generates a normalized path from the GraphPoint array.
This is called by the editor to draw the path under the DragPoints.

fillLookUpTable

void fillLookUpTable()

Fills the look up table with the graph points generated from calculateGraphPoints()
Don't call this too often as it is quite heavy!

getWritePointer

float * getWritePointer()=0

Overwrite this and return a pointer to the data array.

getXValueText

String getXValueText(float value)

This returns a String that can be used for displaying purposes.
You can supply a lambda for the conversion using setTextConverter().
