Method Details

getDatasetType

byte getDatasetType()

Gets the dataset type. Must be one of the dataset type constants defined in this class.

void validate(ChartsVerifier verifier)

Validates the dataset using a verifier.

Broken rules are collected by the verifier.

Parameters:

verifier - the verifier to use for validation

collectExpressions

void collectExpressions(ChartsExpressionCollector collector)
