Method Details

generate

public MethodSpec generate(ObjectField target)

Specified by:

generate in class AbstractSchemaMethodGenerator<ObjectField,ObjectDefinition>

Returns:

The complete javapoet MethodSpec based on the provided target.

formatWhere

protected CodeBlock formatWhere(FetchContext context)

Returns:

Formatted CodeBlock for the where-statement and surrounding code. Applies conditions and joins.

generateSelectRow

protected CodeBlock generateSelectRow(FetchContext context)

This method recursively generates one single row method call. It deduces how each layer of row call should be structured by keeping track of joins and following field references.

Overrides:

generateSelectRow in class FetchDBMethodGenerator

Returns:

Code block which contains the entire recursive structure of the row statement.

getSelectCode

protected CodeBlock getSelectCode(GenerationField field,
 FetchContext context)

generateAll

public List<MethodSpec> generateAll()

Returns:

List of complete javapoet MethodSpec that can be generated for this object.
