Method Detail

builder

public static EdmlDefinition.EdmlDefinitionBuilder builder()

Create a new builder for EdmlDefinition.

Returns:

a new builder for EdmlDefinition

getSource

public String getSource()

Get the source reference, i.e. the table name or resource identifier.

Returns:

the source reference

getDestinationTable

public String getDestinationTable()

Get the name of the destination table in Exasol Virtual Schema.

Returns:

destination table

getDescription

public String getDescription()

isAddSourceReferenceColumn

public boolean isAddSourceReferenceColumn()

Check if a source reference column should be added. If set to true, this adapter adds the source reference as a column named SOURCE_REFERENCE to the Exasol table.

This feature is mainly useful if multiple sources are used (not supported by all dialects). In that case you can filter on the source name.

Returns:

true if a source reference should be added.

getMapping

public MappingDefinition getMapping()

Get the mapping for the document's properties. Typically you want to define fields here to define mappings for this document's properties. But you can also use toJsonMapping mapping here. In that case the whole document is mapped to a JSON string.

You can omit the mapping element to enable auto-inference.

Returns:

the mapping

getAutoInferenceColumnNames

public ColumnNameMapping getAutoInferenceColumnNames()

Get the column name mapping for auto-inference.

Only specify this when mapping is omitted.

Returns:

column name mapping

getAdditionalConfiguration

public String getAdditionalConfiguration()

Get the optional additional configuration options.

Returns:

additional configuration

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:
