Examples with JsonFieldWriter io.atlasmap.json.core.JsonFieldWriter used on opensource projects

Example 1 with JsonFieldWriter

use of io.atlasmap.json.core.JsonFieldWriter in project atlasmap by atlasmap.

the class JsonModule method processTargetFieldMapping.

@Override
public void processTargetFieldMapping(AtlasInternalSession session) throws AtlasException {
    Field sourceField = session.head().getSourceField();
    Field targetField = session.head().getTargetField();
    // Attempt to Auto-detect field type based on input value
    if (targetField.getFieldType() == null && sourceField.getValue() != null) {
        targetField.setFieldType(getConversionService().fieldTypeFromClass(sourceField.getValue().getClass()));
    }
    Object targetValue = null;
    // Do auto-conversion
    if (sourceField.getFieldType() != null && sourceField.getFieldType().equals(targetField.getFieldType())) {
        targetValue = sourceField.getValue();
    } else if (sourceField.getValue() != null) {
        try {
            targetValue = getConversionService().convertType(sourceField.getValue(), sourceField.getFormat(), targetField.getFieldType(), targetField.getFormat());
        } catch (AtlasConversionException e) {
            AtlasUtil.addAudit(session, targetField.getDocId(), String.format("Unable to auto-convert for sT=%s tT=%s tF=%s msg=%s", sourceField.getFieldType(), targetField.getFieldType(), targetField.getPath(), e.getMessage()), targetField.getPath(), AuditStatus.ERROR, null);
            return;
        }
    }
    targetField.setValue(targetValue);
    LookupTable lookupTable = session.head().getLookupTable();
    if (lookupTable != null) {
        processLookupField(session, lookupTable, targetField.getValue(), targetField);
    }
    if (isAutomaticallyProcessOutputFieldActions() && targetField.getActions() != null && targetField.getActions().getActions() != null) {
        getFieldActionService().processActions(targetField.getActions(), targetField);
    }
    JsonFieldWriter writer = session.getFieldWriter(getDocId(), JsonFieldWriter.class);
    writer.write(session);
}

Example 2 with JsonFieldWriter

use of io.atlasmap.json.core.JsonFieldWriter in project atlasmap by atlasmap.

the class JsonModule method processPreTargetExecution.

@Override
public void processPreTargetExecution(AtlasInternalSession session) throws AtlasException {
    JsonFieldWriter writer = new JsonFieldWriter();
    session.setFieldWriter(getDocId(), writer);
    if (LOG.isDebugEnabled()) {
        LOG.debug("{} processPreTargetExcution completed", getDocId());
    }
}

Example 3 with JsonFieldWriter

use of io.atlasmap.json.core.JsonFieldWriter in project atlasmap by atlasmap.

the class JsonModule method processPostTargetExecution.

@Override
public void processPostTargetExecution(AtlasInternalSession session) throws AtlasException {
    JsonFieldWriter writer = session.getFieldWriter(getDocId(), JsonFieldWriter.class);
    if (writer != null && writer.getRootNode() != null) {
        String outputBody = writer.getRootNode().toString();
        session.setTargetDocument(getDocId(), outputBody);
        if (LOG.isDebugEnabled()) {
            LOG.debug(String.format("processPostTargetExecution converting JsonNode to string size=%s", outputBody.length()));
        }
    } else {
        AtlasUtil.addAudit(session, getDocId(), String.format("No target document created for DataSource:[id=%s, uri=%s]", getDocId(), this.getUri()), null, AuditStatus.WARN, null);
    }
    session.removeFieldWriter(getDocId());
    if (LOG.isDebugEnabled()) {
        LOG.debug("{}: processPostTargetExecution completed", getDocId());
    }
}
