Method Details

hasFieldToResolve

public boolean hasFieldToResolve(EntityColumnDetails entityColumnDetails)

Checks if the given entity column details represent a field that needs resolution. This method returns true if the entity column details do not correspond to any relationship mappings, such as @OneToOne, @ManyToOne, @OneToMany, or @ManyToMany.

Specified by:

hasFieldToResolve in interface FieldResolver

Parameters:

entityColumnDetails - The entity column details to be checked.

Returns:

True if the field needs resolution, false otherwise.

handleField

public void handleField(DDLFieldMetadataHolder metadataHolder,
 Map<Integer,List<String>> ddlMetadata)

Handles the resolution of the given entity column details by generating database type information and adding it to the list of column name and database type.

Specified by:

handleField in interface FieldResolver

Parameters:

metadataHolder - The holder containing metadata related to the field.

ddlMetadata - The map storing DDL metadata.

processIdField

private String processIdField(String tableName,
 EntityColumnDetails entityColumn,
 Map<Integer,List<String>> ddlMetadata)

Processes the ID field by generating the database type information.

Parameters:

tableName - The name of the table.

entityColumn - The entity column details.

ddlMetadata - The map storing DDL metadata.

Returns:

The generated database type information for the ID field.

generateSequence

private void generateSequence(GeneratedValueMetadata generatedValue,
 SequenceGeneratorMetadata sequenceGenerator,
 String tableName,
 String columnName,
 Map<Integer,List<String>> ddlMetadata)

Generates the sequence for the ID field if necessary and adds it to the DDL metadata.

Parameters:

generatedValue - The metadata for the generated value.

sequenceGenerator - The metadata for the sequence generator.

tableName - The name of the table.

columnName - The name of the column.

ddlMetadata - The map storing DDL metadata.

checkForDuplicateNameSequence

private void checkForDuplicateNameSequence(Map<Integer,List<String>> ddlMetadata,
 String sequenceNameDefault)

Checks if there is a duplicate sequence name in the DDL metadata and throws an exception if found.

Parameters:

ddlMetadata - The map storing DDL metadata.

sequenceNameDefault - The name of the sequence to check for duplicates.

Throws:

MappingException - if a duplicate sequence name is found.

processTimestamp

private String processTimestamp(EntityColumnDetails entityColumn)

Processes a timestamp column for database creation.

Parameters:

entityColumn - The details of the entity column.

Returns:

The formatted string representing the timestamp column.

isCreationTimestamp

private boolean isCreationTimestamp(EntityColumnDetails entityColumn)

Checks if the timestamp column is marked for creation timestamp.

Parameters:

entityColumn - The details of the entity column.

Returns:

True if the column is marked for creation timestamp, false otherwise.

getColumnNameDatabaseType

private String getColumnNameDatabaseType(EntityColumnDetails entityColumn)

Gets the formatted string representing the column name and its database type.

Parameters:

entityColumn - The details of the entity column.

Returns:

The formatted string representing the column name and its database type.
