Examples with DocumentJavaFieldWriter io.atlasmap.java.core.DocumentJavaFieldWriter used on opensource projects

Example 1 with DocumentJavaFieldWriter

use of io.atlasmap.java.core.DocumentJavaFieldWriter in project atlasmap by atlasmap.

the class JavaModule method processPreTargetExecution.

@Override
public void processPreTargetExecution(AtlasInternalSession atlasSession) throws AtlasException {
    if (atlasSession == null || atlasSession.getMapping() == null || atlasSession.getMapping().getMappings() == null || atlasSession.getMapping().getMappings().getMapping() == null) {
        throw new AtlasException("AtlasSession not properly intialized with a mapping that contains field mappings");
    }
    if (javaInspectionService == null) {
        javaInspectionService = new ClassInspectionService();
        javaInspectionService.setConversionService(getConversionService());
    }
    List<BaseMapping> mapping = atlasSession.getMapping().getMappings().getMapping();
    Object rootObject;
    String targetClassName = AtlasUtil.getUriParameterValue(getUri(), "className");
    JavaClass inspectClass = getJavaInspectionService().inspectClass(targetClassName);
    merge(inspectClass, mapping);
    List<String> targetPaths = AtlasModuleSupport.listTargetPaths(mapping);
    try {
        rootObject = getJavaConstructService().constructClass(inspectClass, targetPaths);
    } catch (Exception e) {
        throw new AtlasException(e);
    }
    DocumentJavaFieldWriter writer = new DocumentJavaFieldWriter(getConversionService());
    writer.setRootObject(rootObject);
    writer.setTargetValueConverter(targetValueConverter);
    atlasSession.setFieldWriter(getDocId(), writer);
    if (LOG.isDebugEnabled()) {
        LOG.debug("{}: processPreTargetExcution completed", getDocId());
    }
}
