Method Details

generate

public no.sikt.graphitron.javapoet.MethodSpec generate(ObjectField target)

Specified by:

generate in class AbstractSchemaMethodGenerator<ObjectField,ObjectDefinition>

Returns:

The complete javapoet MethodSpec based on the provided target.

getHelperMethodCallForNestedField

protected no.sikt.graphitron.javapoet.CodeBlock getHelperMethodCallForNestedField(ObjectField field,
 FetchContext context)

Description copied from class: FetchDBMethodGenerator

Generates a helper method call for nested record type fields. This base implementation generates the root-level helper method call.

Overrides:

getHelperMethodCallForNestedField in class FetchDBMethodGenerator

Parameters:

field - The field to generate the helper method call for

context - The fetch context (unused in base implementation)

Returns:

CodeBlock containing the helper method call, or null to use inline generation

formatWhere

protected no.sikt.graphitron.javapoet.CodeBlock formatWhere(FetchContext context)

Returns:

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

generateSelectRow

protected no.sikt.graphitron.javapoet.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 no.sikt.graphitron.javapoet.CodeBlock getSelectCode(GenerationField field,
 FetchContext context)

generateAll

public List<no.sikt.graphitron.javapoet.MethodSpec> generateAll()

Returns:

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